V. sinuatum subsp. sinuatum var. adenosepalum Murb. and V. sinuatum subsp. sinuatum var. sinuatum L. are these variation. Cross-sections from the taxa's roots, stems, and leaves were viewed under a light microscope for anatomical study. The xylem components play a significant role in the taxonomic root portions. The pith area is a broad region in stem sections, and the upper portion of the epidermis cells is encircled by a distinct indented cuticle layer. The leaves' primary vein is represented by open collateral bundles. Pollen grains in Verbascum sinuatum subsp. sinuatum var. adenosepalum are tricolporate-tricolpate, prolate-spheroidal, and have reticulate exine ornamentation. Similarly, pollen grains in V. sinuatum subsp. sinuatum var. sinuatum are tricolporate-tricolpate, prolate, and have reticulate exine ornamentation. The brown seeds of V. sinuatum subsp. sinuatum var. adenosepalum and V. sinuatum subsp. sinuatum var. sinuatum have an alveolate, deep and wide posterior region, a truncated beak, and a prismatic-oblong shape. The ornamentation of the seed coat is made up of irregular polygonal cells that have noticeable and dense vesicles. The importance of a few traits in the Verbascum variety delimitation has been investigated in this study. For the purpose of supporting ancestral traits in the infrageneric classification and helping with genus systematics, some pollen and seed characters which are typically connected to pollen and seed micromorphological and anatomical patterns can be applied.","PeriodicalId":9653,"journal":{"name":"Celal Bayar Üniversitesi Fen Bilimleri Dergisi","volume":" 96","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140384553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is generally difficult to roll deep of contours having curve and conical forms with available rolling tools. The aim of this study is to design experiments with a roller insert that will be alternative to deep rolling inserts used now and can be fixed on the present tool holders and to investigate the usability of them including curve and conical formed work pieces with the help of this designed tool. For this purpose, a spherical insert with a radius of 1 mm in the form of WNMG was designed based on the WNMG insert model and used in deep rolling of Al6061-T6 material using different forms and parameters. 143, 330, 495 N rolling force, 0.04, 0.08, 0.12 mm/rev feed and 400, 600, 800 rpm spindle speed were selected as rolling parameters. By examining the micro-hardness and surface structure of deep-rolled Al6061 parts, the achievability of the results of existing tools in deep rolling was investigated. At the end of the study, it was determined that the new type of rolling tool produced results similar to the existing tools in deep rolling in terms of micro-hardness and surface morphology, which enabled that the work pieces with curve and conical forms could also be rolled, and that this rolling tool could be used as an alternative in deep rolling","PeriodicalId":9653,"journal":{"name":"Celal Bayar Üniversitesi Fen Bilimleri Dergisi","volume":" 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, synthesis of CdSe/CdS nanorods (NRs) via hot injection method is carried out, followed by preparation of hybrid polymer films from polyethylene glycol monomethyl ether-block-poly(glycidyl methacrylate)-block-poly[2-(diethylamino)ethyl methacrylate] triblock copolymer (MPEG-b-PGMA-b-DEAEMA) at a liquid-air interface. The optical properties of the films are finely adjusted to form optically anisotropic (i.e. dual-color emissive) films by using dyes for the other emitter as desired. Thiazolo[5,4-d] thiazole (TTz)-based dye and 6-carboxy fluorescein were used for this purpose. Tunable emission of TTz dye from blue to green dependent on changing pH value resulted in blue-green emissive polymer films, while red emission of CdSe/CdS NRs caused red emissive films. Phase separation of these materials is achieved by the hexane-insoluble nature of MPEG-b-PGMA-b-DEAEMA and the high solubility of NRs in it. These dual emissive films are promising candidates for waveguides and optical sensors.","PeriodicalId":9653,"journal":{"name":"Celal Bayar Üniversitesi Fen Bilimleri Dergisi","volume":"162 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140256457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Next, the interaction of MC540 with MnO2 in aqueous solution was investigated at various conditions by UV–Vis. absorption and fluorescence spectroscopy and the MC540-MnO2 system to use in fluorescence sensor studies was determined. The sensing ability of the MC540-MnO2 was tested to detect anions as a “Turn-off” fluorescent sensor. The MC540-MnO2 revealed to be high selectivity and sensitivity to detect ClO- ions without being affected by the other thirteen anions. The detection limits for ClO- were evaluated in two different concentration ranges and calculated to be 0.14 µM at 0.33-4.46 µM and 0.38 µM at 5.06-14.30 µM, respectively.

The air gap between the patient's skin and the bolus may cause dosimetric uncertainties. This study aims to dosimetrically investigate the effect of the air gap between the surface and the bolus on dose distribution. Computed tomography (CT) images of the phantom were obtained and transferred to the treatment planning system (TPS). In the TPS, a bolus was placed on the phantom surface and then air gaps were created between the bolus and the surface. The effect of the air gaps between the surface and the 5 mm thick bolus on the dose distribution was analyzed with the point doses obtained from the TPS. For the 6 MV X-ray, it was observed that the air gap negatively affected the surface doses calculated by TPS. Accordingly, an inverse correlation was found between air gap and surface dose. It is recommended that bolus use, especially in curved anatomical regions, should be applied before CT scanning as much as possible. When using bolus material in radiotherapy, it is recommended to be careful not to leave an air gap between the surface and the bolus.","PeriodicalId":9653,"journal":{"name":"Celal Bayar Üniversitesi Fen Bilimleri Dergisi","volume":"4 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139148788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
